Do you mean concave or convex? Convex grinds generally are easy to do on accident, as well as on purpose. Just rocking the file as you push will give it a convex grind. For a concave grind, I just do the majority of the grind flat using files, then use an angle grinder at about a ten degree angle with the blade to hollow grind; the wheel dips in, so depending on the angle with the blade, you can get a dramatic convex grind, or nearly flat.

Pretty much what Caleb said.  To get the "appleseed" edge just roll the file during the stroke.  The hard part is keeping it consistant.

try finishing with stones rather than paper I have been doing a lot of the final shaping of the edges with stones after heat treat sort of rolling the stone down and polishing to an edge.
